Why compiling curl:

/bin/sh ../libtool --mode=link /Users/pjanik/BuildDir/ccache /usr/bin/gcc  -g
-O2   -o libcurl.la -rpath /usr/local/lib -no-undefined -avoid-version  file.lo

netrc.lo getinfo.lo transfer.lo strequal.lo easy.lo security.lo krb4.lo
memdebug.lo http_chunks.lo strtok.lo connect.lo llist.lo hash.lo multi.lo  
rm -fr .libs/libcurl.la .libs/libcurl.* .libs/libcurl.*

ccache: illegal option -- d
ccache, a compiler cache. Version 2.3

Changing the line

CCLD = $(CC)

to

CCLD = "$(CC)"

helped.

I will verify on other platforms first.
